Concierge.com's insider take:

This adorable and slightly naughty Victorian terraced mansion has been a hotel since way before Notting Hill had any cachet. It opened in 1970, the year after the iconic Nic Roeg film Performance (filmed around the corner) came out and, if you squint, it retains a smidgen of Jagger-heyday dirty glamour—which may explain why professional bad boy Colin Farrell stays here now, as does hotel connoisseur and family man Bono. The very definition of shabby chic, the decor is half high-Victorian, half colonial, with claw-foot tubs and a great deal of red velvet. The 24 rooms vary vastly, from a tiny cabin with a TV set tucked into the ample folds of the bed curtains to the famous Round Bedroom suite with the giant circular bed and the restored Edwardian bathing machine—a beautiful, rather dominatrixian arrangement of brass pipe work, the tub of which Kate Moss is rumored to have filled with Champagne. Remember to take advantage of the complimentary evening membership at the nearby Cobden Club, a quirky private venue.
